I have this same bug in my system even when I had Ubuntu 19.10, the upgrade to Ubuntu 20.04 didn't resolved the problem.
My only clue is that this could be a problem with Dropbox, but I'm not sure because I disabled libnautilus-dropbox.so.bak versions 2.0 and 3.0 renaming the file, that's made the Dropbox menu to disappear of Nautilus, but the crash with SIGSEGV after a clean start of the computer it's still happening.
